# What does OG FG mean?

The terms “original gravity” (OG) and “final gravity” (FG) are a measure of the sugar content of the wort before and after fermentation.

## How do you calculate ABV from OG and FG?

Alcohol by volume (ABV) is a measure of how much ethanol is present in a given volume of an alcoholic beverage. ABV is calculated by dividing the number of ethanol molecules by the total number of molecules in the beverage and multiplying by 100.

## How do you determine OG?

To determine the OG of a beer, you need to know the specific gravities of the wort before and after fermentation. The original gravity (OG) is the specific gravity of the wort before fermentation and the final gravity (FG) is the specific gravity of the beer after fermentation.

## Does OG stand for original?

OG, which stands for ‘original gangster’ or ‘original gangsta,’ is a street-slang term that was created in the 1970s by Cecil Holmes and David Mizell, two former high school friends from Los Angeles, CA.

## What is your BAC after 2 beers?

If you are drinking beer that is 5% alcohol, your BAC would be .10 after two beers.

## How many beers is a .08 BAC?

A .08 BAC is the equivalent of 4 beers.

## How is OG calculated beer?

However, the two most common methods are either by using a hydrometer or by using a Plato scale.

## How are gravity points calculated?

Gravity points are calculated by taking the square of the distance between two objects and dividing it by the sum of the masses of the two objects.

## How do you measure original gravity of beer?

To measure the original gravity of a beer, you will need a hydrometer and a trial jar. Fill the trial jar with your beer sample and float the hydrometer in the sample. Read the gravity at the point where the liquid surface intersects with the stem of the hydrometer.
